This deck's main goal is to flood your field using Gilgamesh and Ragnarok to bring back D'Arc. The ideal hand is Swirl, Necro, Ragnarok and either Kepler or Contract with the Gate. To start the combo, fuse Swirl and Necro to make D'Arc using Swirl's effect, normal summon any low level D/D so you can use it and D'Arc to make Gilgamesh, use his effect to place Copernicus and Kepler in your pendulum zones and summon Ragnarok, use his effect to bring back D'Arc. After this depending on what you have leftover you can use Necro to summon another D'Arc or Ghengis, if you didn't use CwtG you can add a lamia to your hand and try for a synchro. Ghost is supposed to help with GY setup or returning the slimes from banishment if things go south. If Gilgamesh goes down, it's usually a good idea to summon Purple Armageddon with his effect.
P.S. This is probably the only "good" deck I will ever make.
